I will be going back to my Halogens
Jeff,

I don’t have any issue w the Osram’s and Appradio4!

Works, yes. But, now your fog lights operate independent of you headlights - they won't turn off when high beams are turned on, unless you manually turn them off.

No issue in IL. Local laws may vary.

That’s exactly what I wanted. I suspect that’s one of the last laws the police will enforce in places where that is the case. Just look at all the goofy headlight configurations that are out there when you drive anywhere at night these days.

I have a set of JDM Astar LED Fogs, no issues, other than the light pattern on them.

I can try Ferrite beads, Worth a shot, if not then back to Halogen. I did notice an odd pattern and a dark spot from the LEDs.. We will see how it works out

Default Re: LED Headlight with fog light issue...

It's funny... I just did an install of the Afeax LED headlamps and stumbled into this fog light issue. Didn't take long to figure out what was up, drew out a plan to do this "piggy back" relay and thought I wonder if someone on the registry has done this... the answer is always yes. This really is a fantastic archive for our cars.

Quick product review: the Afeax LED headlamp replaacement from Amazon (B07BWBRDJ5) $85.99 for the pair.

The install was straightfoward. The bulb almost fits in the headlamp bucket, but does fit under the retaining ring, so if you are careful to keep it "eve" as you install it, it will go in straight and not interfere with anything.

The bulb looks a little "gimmicky" but as night fell i really was quite impressed with the beam pattern. Here's a pic of the unit installed and the low beam pattern on the highway after a few rounds of trial and error adjustments:





Ok... what did I do wrong here, these images are blowing up the thread

BUT

Now time to post my solution I used on my 1990

**Disclaimer: Findings based on my 1990 and FSM, other years may vary**

In the FSM the shows that the Fog light relay grounds through the High Beam. When the high beams are activated in the OEM solution, 12v is applied on both sides of the coil for the relay which then causes the lights to turn off.

When we switch to LED, the high beam filament is replace with electronics, so that does not work so well. Most use resistors, which to me, still gives the load of a Halogen/ Filament light, yes it works, but I want the efficiency benefit.

I acquired a socket and relay from a donor harness I have, I added the relay to my harness to accomplish what I need. Here are the details:


Find the Fog Lamp relay. in my 1990 it is the furthest to the right under the dash.. Look for the Light Green wire. that is the wire you need to manipulate..

Unpin the LT GRN from the current relay move it to 86 of the added relay.

Pin a new wire in the spot where you removed the LT GRN (it is either 85 or 86), Pin the other end of this wire to 87a of your added relay.

On the added relay, Pin 30 and Pin 85 are both connected to ground.

Done, no wires cut, not relays tampered with. I have not installed LED Headlights just yet, but got the car ready for them. So this should work without issue. works fine with my current lights. I will be adding LED Headlights and LED Fog Lights soon.

A schematic...would be nice, Jeff!
